Ibhokisi lephepha umehluko phakathi kokuphrinta kwe-UV ne-gold foil
Isibonelo, izembozo zezincwadi zinyatheliswa nge-foil yegolide, amabhokisi esipho ukuphrinta kwe-foil yegolide, izimpawu zokuhweba kanyeugwayi amabhokisi, utshwala, nezingubo kuyizinto zokunyathelisa nge-foil yegolide, kanye nokunyathelisa amakhadi okubingelela, izimemo, amapeni ngephepha legolide. Imibala namaphethini kungenziwa ngezifiso ngokwezidingo ezithile.
Izinto eziyinhloko ezisetshenziselwa ukunyathela okushisayo yi-electrochemical aluminium foil, ngakho-ke ukunyathela okushisayo kubizwa nangokuthi i-electrochemical aluminium hot stamping; Izinto eziyinhloko ezidlula ku-UV ziyi-inki equkethe ama-photosensitizer ahlanganiswe nezibani zokukhanyisa ze-UV.
1. Isimiso senqubo
Inqubo yokuphrinta i-gold foil isebenzisa umgomo wokudlulisa ngokucindezela okushisayo ukuze idlulisele ungqimba lwe-aluminium ku-aluminiyamu e-anodized ebusweni be-substrate ukuze kwakheke umphumela okhethekile wensimbi; ukuqiniswa kwe-UV kufezwa ngokomisa nokulungisa i-inki. ngaphansi kokukhanya kwe-ultraviolet.
2. Izinto eziyinhloko
Inqubo yokuhlobisa yokunyathelisa. Shisisa ipuleti lokunyathelisa lensimbi, ufake i-foil, bese ucindezela umbhalo noma amaphethini egolide ezintweni ezinyathelisiwe. Njengoba izimboni zokunyathelisa nokupakisha i-foil yegolide zithuthuka ngokushesha, ukusetshenziswa kwe-electrochemical aluminium stamping kuya ngokuya kusabalala.
Isisekelo sokuphrinta i-foil yegolide kufaka phakathi iphepha elijwayelekile, iphepha lokunyathelisa uyinki njengoyinki wegolide nesiliva, ipulasitiki (PE, PP, PVC, amapulasitiki obunjiniyela njenge-ABS), isikhumba, ukhuni, nezinye izinto ezikhethekile.
Ukuphrinta kwe-UV kuyinqubo yokuphrinta esebenzisa ukukhanya kwe-ultraviolet ukuze komise futhi kuqinise uyinki, okudinga inhlanganisela ye-inki equkethe izinto ezithinta ukukhanya kanye nezibani zokupholisa ze-UV. Ukusetshenziswa kokuphrinta kwe-UV kungenye yezici ezibaluleke kakhulu embonini yokuphrinta.
Uyinki we-UV umboze amasimu afana nokuphrinta kwe-offset, ukuphrinta kwesikrini, ukuphrinta kwe-inkjet, kanye nokuphrinta amaphedi. Imboni yokuphrinta yendabuko ngokuvamile ibhekisela ku-UV njengenqubo yomphumela wokuphrinta, ehilela ukugoqa ungqimba lwamafutha acwebezelayo (kufaka phakathi amakristalu akhanyayo, acwebezelayo, afakwe ngaphakathi, impuphu ka-anyanisi wegolide, njll.) kuphethini oyifunayo ephepheni eliphrintiwe.
Inhloso eyinhloko ukwandisa ukukhanya kanye nomphumela wobuciko womkhiqizo, ukuvikela ubuso bomkhiqizo, ukuba nobunzima obukhulu, ukumelana nokugqwala nokungqubuzana, futhi akuthambekeli ekuklwebhekeni. Eminye imikhiqizo ye-lamination manje isishintshelwa ekumbozweni kwe-UV, okungahlangabezana nezidingo zemvelo. Kodwa-ke, imikhiqizo ye-UV akulula ukuyibopha, futhi eminye ingaxazululwa kuphela nge-UV yendawo noma ukupholisha.
